WebIt is the power to which a concentration is raised in the rate law equation. For example, for the reaction xA + yB ---> products, the rate law equation will be as follows: Rate = k … WebThe rate law is experimentally determined to be: rate = k [NO 2] 2. Therefore, we would say that the overall reaction order for this reaction is second-order (the sum of all exponents in the rate law is 2), but zero-order for [CO] and second-order for [NO 2 ]. The reaction order is most often a whole number such as 0, 1, or 2; however, there ...

WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, where k is a proportionality constant called the rate constant and n is the order of the reaction with respect to A. shared storyWebMar 13, 2016 · The answer says no, the rate constant can never be negative because the Rate can never be negative, since Rate=k [R] n. I don't feel completely comfortable with this answer/reasoning, mostly because the rate law for reactants do seem to have a negative rate, where the concentration decreases over time. pool with lazy river plans
